Initialization
==============

The following inputs control how a calculation is initialized.
They must be defined with the prefix ``mfix``:

|                      | Description                                                           |   Type      | Default      |
+======================+=======================================================================+=============+==============+
| do_initial_proj      | Perform an initial projection.                                        |  Bool       |  true        |
+----------------------+-----------------------------------------------------------------------+-------------+--------------+
| initial_iterations   | Number of pressure iterations to execute before time-marching.        |  Int        |    3         |
+----------------------+-----------------------------------------------------------------------+-------------+--------------+
| scale_init_dt        | Factor by which ``dt`` is scaled in the initial iterations and step.  |  Real       |  1.0         |
|                      | Must be a value <= 1.0                                                |             |              |
+----------------------+-----------------------------------------------------------------------+-------------+--------------+
| restart              | If set, then restart from this file rather than from scratch.         |  String     |   None       |
